• Article: Gold catalyzed propargylic substitutions: Scope and synthetic developments

  O. Debleds, E. Gayon, E. Vrancken, J.M. Campagne
  [show abstract] [hide abstract]
  ABSTRACT: This personal account summarizes our recent developments in gold-catalyzed direct substitutions on propargylic (allylic, benzylic) alcohols, with various nucleophiles (and bi-nucleophiles) based on the σ- and/or π-acidity of gold(III) complexes. Synthetic developments are also briefly described.

  ABSTRACT: The use N-sulfonyl-protected hydroxylamines as bi-nucleophiles in iron-catalyzed propargylic substitutions allows the selective one-pot synthesis of four classes of substituted isoxazoles or isoxazolines from the same propargylic alcohols (21 examples) by simply tuning the nature of the base.
